The synthesis by hot pressing and wide-band (10 Hz-1 MHz) magnetoelectric (ME) characterization of bulk composites of nickel zinc ferrite Ni{sub 1-x}Zn{sub x}Fe{sub 2}O{sub 4} (NZFO) (x=0-0.5) and lead zirconate titanate (PZT) are reported. Hot-pressed samples show an order of magnitude improvement in ME voltage coefficient compared to sintered samples. Frequency dependence of ME coefficients show a three order of magnitude enhancement at electromechanical resonance. The ME coupling is maximum for samples with equal volume of ferrite and PZT. The strongest ME interactions are measured for samples of NZFO (x=0.2) and PZT.
